    New substances with different properties are formed.

    Solids, liquids, or gases may form.

    Step-by-step explanation:

    A is wrong. Atoms of one element do not change into atoms of another in chemical reactions.

    D is wrong. Many reactions spontaneously absorb heat.

    E is wrong. Many reaction mixtures are so unstable that they must be cooled to prevent the reaction from going so fast that an explosion might result.
